deploy_shiny_aws
I recently want to deploy my intern company’s R shiny on aws so that everyone can use it. I googled some tutorials but some of them is outdataed, so I just want to write one to document it. (Just in case I need to deploy shiny again in the future).
I mainly used tutorial from here: https://tm3.ghost.io/2017/12/31/deploying-an-r-shiny-app-to-aws/
Today I will go over xxxx things:
- Create an instance on aws
- Deploy a sample R shiny on aws
- Set up username and password when login the shiny
Step 1: Create an instance on aws
If you are a student, you can google aws student and sign up there by using your edu email to get some credits. Here, I assume you already have the account.
Click on the EC2 button, then Launch Instance, it will lead you to choose AMI page. Select the newest Unbuntu Server.
Then you goes to Step 2: Choose an Instance Type, here I choose t2.micro since it’s free, you can choose your own depends on you need. Check this link to select the instance type you need: https://aws.amazon.com/ec2/instance-types/. Then click Next: Configure Instance Details. Don’t click Review and Launch.
Leave the Step 3: Configure Instance Details as it is, and click Next: Add Storage.
Change Size (GiB) to 16GB as recommend by some R bloggers. Click Next: Add Tags.
Click Add tag and type the name under the key. Here, mine is sample_shiny. Next, click Next: Configure Security Group.
This section is really important. It allows users to access the r studio and the shiny. Please choose the configuration as specified below. Then click Review and Launch.
Almost done!!! Click the Launch button and choose Create a new key pair. Type in the key name you want, mine is sample_shiny. Then click Download key pair and save the download file in a folder you want. As a demonstration, I saved mine on Desktop, you should save it to a more secure location just in case you won’t accidentally delete it. After you down, you should see a file named your_key_name.pem in your specified folder location. Lastly, click Launch Instances.
If you see this “Your instances are now launching”, that means you are good to go. Click on the Instance ID in the red box.
Connect to instance by clicking Connect and you should see a window pops up that tells you how to access your instance. Open your terminal on your laptop; I use the Terminal app on Mac. cd to the folder that store the key you just downloaded; mine is in Desktop.
Copy and paste the commnad line from step 3 in popped up window to terminal.
Mine is chmod 400 sample_shiny.pem.
Copy and paste ssh -i "sample_shiny.pem" ubuntu@yourpublicDNS to terminal. You can find this from Example in popped up window.
Type yes to Are you sure you want to continue connecting (yes/no)?.
If you see something like ubuntu@xxx, you are connected.
Step 2:
